[Also in Division F1] A current limiting circuit breaker having an arc-chute such as that described in Specification 1,196,798 is provided with a muffle 40 for the arc gasses, the muffle comprising first a set 51 of parallel, closely spaced plates 58A lying parallel to the direction of flow to cool the gasses and having parts 58B<SP>1</SP> at an angle to the plates 58B to create turbulence and prevent reflected pressure waves occurring and secondly a set 53 of parallel closely spaced plates 60 lying across the direction of flow and provided each with a plurality of small holes, holes in adjacent plates being out of alignment. In the circuit breaker (Figs. 1, 2, not shown) the arc is driven against a wall 39 having slots 39A through which the gases escape, but the arc cannot move. The muffle is longitudinally divided by insulating barriers 49A-49C so increasing the arc path that restriking within the muffle is impossible. Adjacent plates 60 are separated by narrow spacers 62 and second, smaller set 55 of plates 60 is spaced from the first by a large spacer 54; the spacers 62, 54 are divided by cross members so as to reduce the spaces between the plates to filter out the appropriate frequencies of the sound waves. The assemblies of plates, &c. are placed, in abutment, inside a pair of insulating wrappers 67, 68 and then slid into a metal casing 42 where they are retained by bolts insulated by tubes 70. The casing 42 is provided in its remote end with openings, aligned with the openings in spacer 54, for the cooled gasses to escape. The spacers 62 may be of metal or vulcanized fibre and spacer 54 and wall 39 of glass fibre reinforced melamine.

Liquid is evaporated by spraying it through jets 13 on to a tube 14, so that the liquid flows over the outer surface of the tube in the form of a film, while hot water, which has been withdrawn from the cooling-jacket of an engine 31, flows through the tube and gives up heat to the film of liquid, and/or the inside of the tube is supplied with steam from source 29, when the hot water from the engine-jacket does not transfer sufficient heat for the evaporation of the liquid or when the engine is not in operation. Valves 33 and 30 are operated to control the supply of hot water, from the jacket of engine 31, and/or steam from source 29 to the interior of tube 14. The apparatus shown is surrounded by a shell 11 which is evacuated by pump 25, and is suitable for the production of distilled water from sea water. The sea water is introduced into the system through inlet 23, and part of it is used as seal-water for pump 25. The bulk of the sea water flows to the evaporator-jets 13 via preheater 15 where it is heated by the steam produced by evaporation from the film flowing over tube 14. The condensate, i.e. distilled water, formed in preheater 15, is withdrawn from the system through conduit 50. A test panel is connected to the conduit 50 via three-way valve 48. Some of residual brine in hot well 17 is recirculated to the jets 13 and some is discharged via valve 20. The evaporator may be operated at an absolute pressure of 2¢ "mercury, the sea water being evaporated at a temperature of approximately 110F. using engine-jacket-water at a temperature of about 150F.

Dewatered organic waste is fed to a furnace by a tube 42 having a rotatable vertically adjustable distributer cone 44 at its outlet, so that the particle size and direction of the sludge projected against the walls of the space 28 above a fluidized bed can be adjusted to maintain the desired temperature of the outlet gases. The preheated combustion air is fed to the fluidized bed at such a rate that jets of the material of the bed are projected into the space 28 so that fine particles and ash are entrained in the outlet gases, and returned above the bed from a separator 64. The temperature of the bed is regulated by controlling an air preheat by-pass and an auxiliary burner 26. The lower part of the furnace is tapered to allow for the increase in gas volume caused by the drying and combustion of the sludge. By adjusting the height above the bed at which the particles hit the walls, the suspension time above the bed and hence the heat transfer to and evaporation from the particles is controlled.
